Greece is set to vote on its bailout. The main event begins at 10 p.m. local time (3 p.m. ET), and is likely to drag on into early Thursday morning. Prime Minister Alexis Tsipras will need support from outside his coalition. As Business Insider's Mike Bird reports, "Tsipras' Syriza party and the Independent Greeks combined have 162 of the 300 seats. The Independent Greeks have already said they'll oppose the deal, and there will most likely be a decent chunk of Syriza rebels." Greece's two-year yield is up 63 basis points at 26.65%.

China GDP topped estimates. The Chinese economy grew at a 7.0% clip in the second quarter, edging out the 6.9% that economists were anticipating. Though the number was stronger than expected, it was the lowest reading since the first quarter of 2009. As for the other data, industrial production, retail sales, and fixed-asset investment all topped forecasts. China's yuan was little changed at 6.2092 per dollar.

The Bank of Japan kept policy on hold and downgraded its outlook. Japan's central bank held its key rate unchanged, near zero, at Wednesdays' meeting and lowered its economic forecast. The BOJ now sees the Japanese economy growing at 1.7% and inflation of 0.7%, through the fiscal year ending in March 2016. Those forecasts are down from the previous estimate of 2.0% and 0.8%, respectively. Japan's yen is down 0.1% at 123.53 per dollar.

UK jobs data disappointed. The UK's claimant count change unexpectedly rose by 7,000; economists were forecasting a drop of 8,900.

The British pound is weaker by 0.1% at 1.5623.

Bank of America beat. The investment bank announced earnings of $0.45 per share, which included a one-time adjustment of $0.04. The results topped the $0.36 Wall Street estimate. Revenue rose 1.8% to $22.35 billion, beating the $21.83 billion that analysts were expecting." Solid core loan growth, higher mortgage originations, and the lowest expenses since 2008 contributed to our strongest earnings in several years, as we continued to build broader and deeper relationships with our customers and clients," CEO Brian Moynihan said.

Yum Brands announced 4th straight quarter of sliding sales. The quick-service restaurant operator announced earnings of adjusted earnings of $0.69 per share, easily outpacing the $0.62 that Wall Street was expecting. Revenue fell 3.1% to $3.11 billion, shy of the $3.19 billion that analysts were anticipating. Same-store sales in China continued to reel after last July's food scandal, cratering 10% in the quarter, much worse than the 8.4% that was expected.
